.TH STRIP 1 "Oct 5, 2007"
.SH NAME
strip \- strip symbol table, debugging and line number information from an
object file
.SH SYNOPSIS
.LP
.nf
\fBstrip\fR [\fB-lVx\fR] \fIfile\fR...
.fi

.SH DESCRIPTION
.sp
.LP
The \fBstrip\fR command removes the symbol table \fBSHT_SYMTAB\fR and its
associated string table, debugging information, and line number information
from \fBELF\fR object files. That is, besides the symbol table and associated
string table, the following sections are removed:
.sp
.in +2
.nf
\&.line
\&.debug*
\&.stab*
.fi
.in -2
.sp

.sp
.LP
Once this stripping process has been done, limited symbolic debugging access is
available for that file. Therefore, this command is normally run only on
production modules that have been debugged and tested.
.sp
.LP
If \fBstrip\fR is executed on a common archive file (see \fBar.h\fR(3HEAD)) in
addition to processing the members, \fBstrip\fR removes the archive symbol
table. The archive symbol table must be restored by executing the \fBar\fR(1)
command with the \fB-s\fR option before the archive can be linked by the
\fBld\fR(1) command. \fBstrip\fR produces appropriate warning messages when
this situation arises.
.sp
.LP
\fBstrip\fR is used to reduce the file storage overhead taken by the object
file.
.SH OPTIONS
.sp
.LP
The amount of information stripped from the  \fBELF\fR object file can be
controlled by using any of the following options. The following options are
supported:
.sp
.ne 2
.na
\fB\fB-l\fR\fR
.ad
.RS 6n
Strip line number information only.Does not strip the symbol table or debugging
information.
.RE

.sp
.ne 2
.na
\fB\fB-V\fR\fR
.ad
.RS 6n
Prints, on standard error, the version number of  \fBstrip\fR.
.RE

.sp
.ne 2
.na
\fB\fB-x\fR\fR
.ad
.RS 6n
Does not strip the symbol table. Debugging and line number information might be
stripped.
.RE

.SH OPERANDS
.sp
.LP
The following operand is supported:
.sp
.ne 2
.na
\fB\fIfile\fR\fR
.ad
.RS 8n
A path name referring to an executable file.
.RE

.SH ENVIRONMENT VARIABLES
.sp
.LP
See \fBenviron\fR(7) for descriptions of the following environment variables
that affect the execution of \fBstrip\fR: \fBLANG\fR, \fBLC_ALL\fR,
\fBLC_CTYPE\fR, \fBLC_MESSAGES\fR, and \fBNLSPATH\fR.
.SH EXIT STATUS
.sp
.LP
The following exit values are returned:
.sp
.ne 2
.na
\fB\fB0\fR\fR
.ad
.RS 6n
Successful completion.
.RE

.sp
.ne 2
.na
\fB\fB>0\fR\fR
.ad
.RS 6n
An error occurred.
.RE

.SH FILES

.SH NOTES
.sp
.LP
The symbol table section is not removed if it is contained within a segment or
if the file is a relocatable object.
.sp
.LP
The line number and debugging sections are not removed if they are contained
within a segment or if their associated relocation section is contained within
a segment.
.sp
.LP
The \fBstrip\fR command is used to remove a standard predefined set of sections
from an ELF object file. To remove a user specified section by name, see
\fBmcs\fR(1).
